This is a GitWatcher lab, experimenting with Goliath asyncronous ruby web server framework, Grape APIs, gitwatcher.com data on MongoLAB/MongoDB and Heroku PAAS. Here they are, the Heroku working examples used during the tests:
- http://ggm.herokuapp.com/v1/categories
- http://gitwatcher.com/categories.json This is currently off-line, because Gitwatcher is going to be rebuilt from scratch !
UPDATED (see the end page):
- add new example Rails-api micro-framework + Grape endpoint
- (based on Rails 4.0.0.beta1)
ab is a single-threaded command line computer program for measuring the performance of HTTP web servers. Originally designed to test the Apache HTTP Server, it is actually generic enough to test any web server.
Following the comparison between Rails 3 and Goliath 1 JSON API.
The following ApacheBench, has been run on Heroku Cedar single Web Dynos, on Ruby 1.9.3p194, MongoLAB/MongoDB. Goliath 1 responds to 100 cuncurrent calls in 1.826 seconds, with a medium of 54.76 requests per second:

the banchmark of Rails on the same machine get back an apr_poll timeout (70007). That happen serverving Rails both with thin or webrik:

Rails-api micro-framework (Rails 4.0.0.beta1) + Grape endpoint ( see the source code ) This slim rails 4 API framework, is faster than full rails but twice slower than Goliath anyway
